The end product of carbohydrate metabolism is

Photosynthesis and respiration are similar because:
$I$. In eukaryotes,both processes occur in specialized organelles.
$II$. $ATP$ synthesis in both is explained by the chemiosmotic theory.
$III$. Both use an $ETC$ (Electron Transport Chain).

$(B)$ Energy released in fermentation	$(II)$ Less than $1$
$(C)$ $RQ$ of glucose	$(III)$ $1$
$(D)$ Net $\text{ATP}$ produced in fermentation	$(IV)$ $2$
